推荐答案

您需要使用

You need to use the treeview control[^]. If you google "winforms treeview" there are many customones out there that might be better suited to your needs.

在mytreeview的相同位置使用另一个树视图mysearchedTreeview，更改其可见状态搜索发生后，两个treenodes

Use another treeview which is mysearchedTreeview at same location of mytreeview ,change the visible states of the two treenodes once searching is happend

private void txbsearch_textchange(object sender,eventArgs e)
{
if(txbsearch.Text.Length>0)
{
mySearchNodeTxt(mytreeview.nodes,txb.text);
mytreeview.visible=false;
mysearchedTreeview.visible=true;
}
else
{
mytreeview.visible=true;
mysearchedTreeview.visible=false;
}
} 

private mySearchNodeTxt(TreeNodeCollection m_TreeNode, string searchtxt)
        {
            foreach (TreeNode Searchnode in m_TreeNode)
            {
                if (Searchnode.Text.ToLower().Contains(searchtxt.ToLower()))
                {
                 mysearchedTreeview.nodes.add((TreeNode)Searchnode.Clone());


                }

                SearchNodeTxt(Searchnode.Nodes, searchtxt);
                
            }
            
        }
